Every market we collect.
Charts
Each storefront's own chart, in its own country — the closest public signal to sales where none is published. A country missing from a list is one we don't collect there, not one where the game doesn't chart.
No United States chart position — it charts only in the markets below.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
About
Species: Unknown is a first-person survival horror game, playable in co-op with up to 4 players (private or public servers) or solo. You play as a mercenary sent aboard an abandoned spaceship. Your job? Execute high-risk contracts, make it out alive, and claim your reward. But keep in mind that you’re not alone. Something is hunting you…
Form a squad of up to 4 players to take on different contracts with escalating difficulty. Each mission plays differently depending on your objective, your teammates, the map and which of the 5 intelligent threats is stalking you. No one survives alone, but you can try.

Proximity Chat & Radio are available: distance matters, walls matter. Proximity Chat is bringing more tension, sometimes chaos, and unforgettable moments to your co-op sessions.

Every contract drops you into a different nightmare. Whether you're tasked with extracting a black box, capturing or eliminating an unknown threat, or even destroying the ship to prevent the creature from escaping… Each mission demands a specific strategy and none of them are easy.
The specimen is chosen procedurally from a growing roster of terrifying monsters. Each one comes with distinct behaviors, hunting patterns, strengths, and weaknesses. You’ll need to investigate your surroundings to gather vital clues and identify the threat in order to proceed smoothly (or not). Do your job and get rewarded, or die without anyone knowing.

Strategize as a group, make smart use of your tools that can turn the tide, if only for a moment:
Motion Tracker : Detect nearby movement and prepare for what's coming
Shield : Block deadly attacks and buy time for your team
Health Syringe : Heal yourself or allies in the heat of battle
Mini-Map : Navigate pitch-black corridors with real-time positional data
Guns won’t always save you. Some threats are too resistant or simply untouchable. But the right weapon, found at the right time, can help you push through or even take the creature down.

The higher the risk, the higher the reward. Completing contracts earns you credits you can use to:
Upgrade your gear
Buy new tools
Customize your appearance
Gather lore and build your own creature museum

Je mets l'avis négatif jusqu'à qu'on arrive à évacuer en mode facile avec "010". On arrive à la navette, il est juste derrière nous, il rentre, donc on ressort, on manque d'endurance et les 200 zombies nous bloquent donc on meurt, on revient et même chose jusqu'à la limite de réapparition. Les armes ? Oui, mais quand une énorme bestiole te court après tu peux pas prendre le temps de shoot les zombies. C'était le mode facile et on était 2, je pense que c'était pas super bien équilibré.
Despite this game being Early Access, I can confidently say it is well worth the money. Even the full supporter package if you are feeling generous. There is a definitive polish to the visual design of the game, the character movement, and the mission mechanics. The weapons feel appropriately strong or weak depending on the creatures you face, and the game rewards team play when engaging in combat. However, monster combat is not the only core mechanic. Puzzle solving is, and in this vein, the game also does well. Each mission presents a different location of a ship with a different puzzle to solve, and the nature of the puzzle will be slightly different each time. Combine this with the fact that each enemy creature poses a unique threat and unique challenge to defeat or avoid it, provides avenues for a lot of replayability. This is even now with only one map and a handful of enemy creatures. The character customisation is very good, considering the price point. The upgrade packages like your armour, stamina and mini-map all feel rewarding and reasoanably price-scaled I would say, althought I have not delved too deeply into it yet. My only gripes with the game so far is that sometimes the Menu UI can feel a little clunky to use and some other key input hardships. The Menu UI requires sometimes a click, or sometimes a button press. But it's not always immediately clear which it needs, or if either will work. There seems to be a long delay between the menu screen appearing and the ability to actually interact with it. This exacerbates this issue for me. As for key input issues, I'll give an example: if you pick up a non-weapon item and carry it, pressing the "Swap Weapon" button will immediately drop the item and then equip NO weapon in its place. That's a bummer for obvious reasons. It should actually swap to a weapon, so long as you have one. I usually don't go for this kind of game, but this is impressive so far. I hope the roadmap continues to build on what is undoubtedly a solid foundation.

This and every other Pro feature is free until October 20, 2026. A free account is all it takes.
Reviews, worldwide (the counter carries no country): 18.86/day in the week to Jul 31 → 19.57/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,419 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
